Purpose: To evaluate the relationship between visual outcome and the photoreceptor inner segment/outer segment (IS/OS) layer status in patients with macular edema of any etiology. Design: Cross-sectional study. Participants: Forty-eight eyes diagnosed with macular edema Methods: Patients with macular edema of any etiology We obtained simultaneous visual acuity and optical coherence tomography (OCT) of patients with macular edema using a spectral-domain (SD) OCT system. The device recorded retinal thickness on tomography.
SD OCT was recorded repeatedly in patients before and after treatment with an anti-vascular endothelial growth factor agent or triamcinolone, and the central thickness, IS, and OS were measured. The IS/OS ratio was calculated, and the data were analyzed statistically. Main outcome measures: Visual acuity. Results: Forty-eight patients (48 eyes: 21 male and 27 female;…
